I tried to download my web files with FTP. It takes a long time (about one complete day). Suddenly, it stopped downloading. I tried to open my website, but it doesnt accept. the browser gives me:

Network Error (tcp_error)

A communication error occurred: "Operation timed out"
The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests. You may wish to try again at a later time.

Sounds like a shithouse server, or a shithouse connection to the net at your house.
Unless your site is like 100gb of data it should not ever take that long to download.
In any case ftp is not the issue.
